M5Stack Chain Angle Potentiometer Knob with STM32G031
The M5Stack Chain Angle is a potentiometer input module from the Chain series with an integrated STM32G031G8U6 microcontroller. Turning the potentiometer knob changes the voltage at the sampling port within a defined range. The integrated ADC converts this signal into a digital value with up to 12-bit resolution. A programmable RGB LED enables status indication and interactive feedback. The potentiometer cap features brick-compatible mounting holes for creative structural connections. The module communicates via a UART serial cascading protocol at 115200 bps and can be connected to other Chain devices via two HY2.0-4P extension interfaces. The included Chain Bridge Connector allows easy integration into existing Chain systems. The Chain Angle is suitable for human-machine interfaces, smart home controls, and motor speed regulation.
